BRAIN-ADJUSTING DEVICE FOR HARVESTERS.

SPECIFICATION forming part of Letters Patent No. 278,492, dated May 29, 1883,

Application filed October 10. 1882. (N0 model.)

To all whom it may-concern Be it known that .I, MAURICE E. BLooD, 1'61, siding at Sycamore, in the county of De Kalb and State of Illinois, and a citizen of the United States, have invented new and useful Improve-t ments in Grain Adjusting Devices for Harvesters, of which the following is a full description, reference being had to the accompanyingdrawings, in which- Figure 1 is a top or plan view, showing a portion of the receiving-platform, binding-taimprove the means'for operating such grain straightening and delivering devices; and its nature consists in the several parts and combination of parts hereinafter described, and

r set forth as new inthe claims.

In the drawings a complete machine is not illustrated,but only so much as is deemed necessary for showing the location and arrangements of the devices which form the subjectmatter of this invention. p

Arepresents a grain receiving platform, supported at its .front side on a sill, A having thereon the ordinary sickle-guard, carrying a sickle, as usual, and having at its rear side a table,,A., for bindingthe grain.

B is a guide board standing diagonally across the innerforward corner of the platform A,for eveni-n g the butts and holdingthem in place when swept around by a rake, the

- platform A being intended for use with'a platform-rake.

B B arecross-sills,between which the main or drive wheel is located. I

. O O are reel-posts supporting. a reel in the usual manner.

D D DU areframe-pieces supporting the binder-operating mechanism, the binding-arm, and other devices, and supported upon suitable posts or uprights, D

The parts so far referred to can be of any well-known form of construction and arrangeinent suitable to furnish a platform 'l'orthe grain,-a table on which the grain can be bound, and a frame-work for the drive-wheel, binding devices, and appliances pertaining to a self binding harvester.

Fis a wheel or disk formed of a rim orouter portion, 0, with arms and spokes cjoining the rim to a center, 0. This disk or wheel F has located on its periphery a series of teethfour, as shown-each having an acting portion, (a, and a heel, a, and pivoted between the face of the rim 0 and an ear, I), so as to be free to swing to project theacting portion into position for use, or drop into position to be out of use while. the wheel or disk is rotated.

t .G is a cam or guide way formed of a segmental flange or rim, (Land arms or spokes d, connecting the flange or rim to a center or hub, 1 from which hub extends out another arm or spoke, d". This cam is arranged in such relation to the periphery of the wheel F and the teeth a as to be engaged in succession by the heels a of the teeth, and hold their points or acting ends projected to engage the grain and carry it forward, and otherwise act thereon, as hereinafter described.

His a strip of sheet-iron or other suitable material, having a curved portion to coincide with the curve of the segment or flange Gr, and connected to such flange bylugs or projections 0, extending out from the flange,and to which the strip H is attached byrivets or otherwise.

This strip H acts as aretainer to be pressed on the grain at the butt-end and hold the butts back, and also as a guard against the entrance of the grain to the driving gear or devices of the wheel or disk F.

I is a rod of wrought-iron or other suitable 9 ing rod or bar for the disk or wheel F, and its for the-heads and hold them back. This retainer I is attached, as shown,-to the suspendextreme free end has a downward curve to cause it to lie in a lower plane than the retainer H when the disk is standing vertical, and have it act to some extent against the travel of the grain.

J is a rod or bar, the lower end of which is pivotally connected by a suitable pin or bolt to an ear, f, on the segment or flange G, and its upper end has a slot, g, for the passage of a rod, J, mounted on the frame-pieces D and E, allowing the bar to slide on such rod and to be turned thereon to change the position of the disk or wheel F, and also its inclination in relation to the platform. I

K is a lever, the inner end of which is connected with the pin or bolt attaching the bar J to the ear fithe-upper end of which is arranged to be within reach of the driver of the machine. This lever, near its upper end, engages with a. rack-bar, K, and by means of this lever the wheel or disk F can be turned to stand at difterentinclinations, both vertical and horizontal, and when the disk is set at the proper inclination the lever can be locked to the rack-bar K, holding the disk or wheel in its set position. The first effect produced upon the disk by moving the lever K from the center of the rack-bar toward either end is to swing the disk in a horizontal plane and without canting it; but as the swing of the lever is increasedthat is, as it is moved nearerthe end of the raclebar-further horizontal swing of the disk will be prevented by reason of edges of the slot g pressing upon opposite sides of tlte rod J, or, in other words, pinching said rod. moved, the effect upon the disk will be to can't it to either of "the positions shown in Figs. 4

' I and 5, dependent upon which way the lever is moved. The feasibility of thus canting the 7 disk is furtherassured by reason ofits weight and the engagement of its teeth with the grain on the platform, and when once canted it will be apparent that the grain will act as a wedge or stop to prevent any tendency of the disk to return to a vertical position, which can only be done by forcing it around with the lever K.

L is a short shaft, on which is mounted the .-wheel or disk F, and supported by the hub or center of the segment or flange G, in which the shaft has its hearing. This shaft has on one end a beveled pinion, /L, which meshes with a corresponding pinion, h, on the end of a shaft, L, the inner end of which is supported in a bearing, 1 on the arm or spoke d of the segment or flange G.

M is a coupling connecting the shaft L with the driving-shaft.

N is the driving-shaft.

0 is a sprocket-wheel on one end of the shaft N, and-driven by a 'chain from the main or drive wheel or othermoving partof the binder or machine.

P is a standard, the lower end of which is Now,if the lever K be still further bolted or otherwise secured to the cross-beam B, and its upper end provided with a bearing,

j, for the shaft N.

The devices or parts represented by the letters J, J, K, K, L, L, M, N, O, and P can be constructed and arranged in some other manner than shown, to suit the style of machine to which the disk or wheel F, cam or segment G,

or in such relation to the platform and grain as will cause it to act on the butts before the grain passes to the binder, and, as shown, a spring-finger, k,is provided to retard the grain at the head end and assist the wheel or disk in straightening oblique-lying grain.

The operation isas follows: The wheel or disk F is turned or swung through the arm or lever K to stand vertical or inclined,as shown in Figs. 3,4,and 5. When standing as shown in Fig. 3, the teeth a will engage the grain near the butt-end and advance the butts faster than the heads, straightening the grain by carrying the butts forward,and this set of the wheel or disk is the one intended for use with the ordinary cut of grain, which falls on the platform with the heads in advance of the butts. WVhen the heads are considerably in advance of the butt-s, the wheel or disk is to beswung or turned into the position shown in Fig. 5, raising the retainer H and lowering the retainer I, allowing more space for the free travel of the butts, and producing a retention on the heads by the contact of the retainer I with the grain, holding the heads back and carrying the butts forward; and when the heads are to have a freer travel than the butts the disk or wheel F is swung or tnrned'into'the position shown in Fig. 4, raising the retainer I and lowering the retainer H, allowing a free space for the travel of the-heads, and produc- ICO IIO

ing a pressure on the butts by which they are held back, so that the disk will act to carry the heads forward faster than the butts. This arrangement enables the driver or operator to entirely control the flow of the grain, and to change such flow as required to produce a proper delivery of the grain to the binder.

, The devices are very simple, and will do the 7 proper relation to the binder for binding purposes. i

The retainers k are secured to the face of theplatt'orm, as shown in Figs. 1 and 2, and are curved upward and have a spring or yielding movement, which will allow the grain to pass readily, and at the same time form a stop or resistance by which the heads will be retarded, and these springs or retainers could be applied and used with some other form of devicethan the disk or wheel F.

The retainer H will always be necessary where the butts only are retarded or held back, and where the heads only are to be retarded or held back the retainer I is all that need be used; but, as in the handling of grain either end is liable to be the one to be operated upon, it is preferred to use both retainers, as shown and described.

The wheel or disk F, with the retainers H and 1, is supportedfrom the cross-rod J'through the medium of the suspending-oar J,'the lower end of which is connected with the 'frame or camway G, and the upper end of which is provided with an elongated slot, so that the wheel F, with the frame G and the retainers H and Lean turn to the right or left, as represented in Figs. 4 and 5. The driving-shaft L does not interfere withthe movements mentioned, by reason of the provision of the universal coupling M, which permits the forward end of the shaft to swing to the right or left with the ad'uster. The swinging movements of the adjuster to the positions represented in Figs.

4 and 5 are effected by means of the inclined lever K, which has its inner end connected with the frame G by a pin, so that by swinging the outer end of the lever the adjuster will be canted the same as though the lever stood in a vertical position, the adjuster turning on the coupling M and rod J as the pivotal points.

What I claim as new, and desire to secure by Letters Patent, is-

1. A rotary disk or wheel arranged to operate on the grain, and provided with a retainer, H, adapted to be brought into contact with the grain at the butts, substantially as and for the purposes specified.

2. A rotary wheel or diskarranged to engage the grain, and provided with a retainer, I, adapted to be brought into contact with the grain at the heads, substantially as and for the purposes specified.

3. A rotary wheel or disk arranged to engage the grain, and provided with retainers H 1, adapted to be brought into contact with the grain on either side of the disk or wheel, substantially as and for the purposes specified.

4.. Arotary wheel or disk,F, having teeth toengage the grain, and a cam or guide way, G, in combination with the retainers H I and suspending-rod J, for operating on-the grain, substantially as and for the purposes specified.
